At least 120 people were killed in Pakistan Thursday in a series of bombing attacks mostly targeting Shiite Muslims and government soldiers. Eighty-six deaths came in a twin bombing in the southern city of Quetta, with scores dying in an initial blast followed by more deaths when a car bomb struck police and rescuers who arrived at the scene. The banned Sunni group Lashkar-e-Jhangvi claimed responsibility for the attack, prompting fears of worsening sectarian violence in Pakistan after more than 400 deaths in 2012.
